SLAT-MACHINE FOR WINDOW-BLINDS.

Specification of Letters Patent No. 10,063, dated October 4, 1853.

T0 all Lo/wm t may concern.'

Be it known that I, ELIHU R. BENSON, of Warsaw, in the county of )Wyoming and State of New York, have invented a new.

original, and useful machine, not heretofore known or used, for the milling, dressing, and wiring of the slats of windowblinds, hereinafter particularly described.

I propose to name the machine Bensons window blind machine.

The drawings referred to in this specification are to be taken as forming a part of it, and are: Figure l, a perspective view of the machine. Fig. 2, a birds eye view of the top thereof. Fig. 3, a view of the slides in the dressing and wiring parts of the machine. Fig. Il, a view of some of the machinery operating the slide in the milling part of the machine. Fig. 5, a perspective View of one of the stickers in the wiring part of the machine.

For convenience and simplicity I shall divide the machine, (in the description of it,) into three parts, viz the milling part, the dressing part, and the wiring part. Each of these parts will be separately described.

1825. The milling part-The otiice of this 1 part is to make the tenons on the ends of the slats, and to place the slats, (after milling) in the dressing part ofthe machine. The letters A, B, O, D, E, F, in Fig. 1, indicate the gearing for operating this part of the machine-(in part) and need no description, except the drawings.

The letters Gr, I-I, I, J, K, L, M, N, R, S, in Fig. l, dcno-te the same part-s, in Fig. l,

and in Fig. 2, and in both Fig. l, and Fig. 2 denote parts of the milling part of the machine.

In Figs. l and 2 J, J, J, J are l guides or posts, forming in all one crib in which the slats are placed, in the rough state, in a pile, across the slide G, each end of the pile resting on the elevated edges of the slide Gr shown in the drawings. These guides or posts are far enough apart to just hold the slats in a perpendicular pile.

In Figs. l, and 2, the letter G is a slide operating back and forth by means of a pin ctwhich protrudes through the slide into an eccentric groove b, b, in the wheel O, Figs. 2 and 4. (Wheel O, is near the top of, and upon the shaft E, see Figs. l, and 4.) When the slide G is drawn out, the pile of slats drops into the notch K, which is deep enough to'receive the bottom slat in the pile. As the slide G passes back, the lower slat, resting in the notch K is thrust forward, under the springs R, It, (hereafter described) to a point directly between the two hollow augers I, I, when the two angers I, I, are drawn up against the two ends of the seat and perform the tenoning, (or milling) of both ends of the slat at once. While the milling is going on, the slide Gr is again drawn out, and the pile of slats in the crib J, J, J, J again drops into the notch K, and the angers are at the same time withdrawn from the first slat, and that slat drops down over the end of the spring N, and as the slide G again moves forward t-he lirst slat, at N, and the bottom slat in the pile at K are both moved forward-the former by the springs at N into the dressing part of the machine and left on the bed m, m, Figs. l and 2, and the latter slat is taken to a point between the two hollow angers I, I, when it is milled, as above described, and so of each successive slat.

The springs at N, Figsl, and 2, made fast at K are pressed do-wn by the slat, as it rests upon them, at the commencement of the milling process; as soon as that process is begun, the slide G is drawn back so far as that the springs N, fly up and present a shoulder, which, as the slide Gr moves forward, drives the slat, just milled, into the dressing part of .the machine, as above stated.

As the slats are shoved along, as above described they pass under the two springs R, R, Figs. l, and 2. These springs are made fast at S, S, only. The other ends of the springs are turned up, at right angles and form two of the guides or posts, J, J, above described.

rIhe two hollow augers I, I, Figs. 1,-and 2, are made to revolve by belts over the pulleys H, II, Figs. l and 2, and they are made to press against the two ends o-f the slat, in the process of milling, and to withdraw themselves from the slats, when milled, as herein described, by means of the two eccentrics P, P, Fig. 4, placed below the wheel O, Figs. 2 and 4 on the shaft E, Figs. l, and 4L. An eccentric strap or arm extends from one eccentric P to one of the carriages L, L, and is fastened to the lower part of it. A like strap passes from the other eccentric P to the other carriage L, L, all so arranged as that the carriages B, Fig. 1, resting on a step D, is moved to revolve by a bevel wheel on shaft C, not seen in the drawings. The slats, in an undressed state are laid into the crib J, J, &c. by hand.

2. The dressing part. The dressing part of the machine is indicated by the letters T, U, V, 1V, X, Y, o and m in Figs. 1 and v2, and letters d, e, f, g, 7L, z', 7a in Fig. 1. They arrangement of the gearing of this part is seen in Fig. 1.

The slat, after being milled, is left by the slide G, as above described, on the bed m, m, Figs. 1, and 2. The slide V then in the place of the slide V in Fig. 2, (but not in the place of the slide V Fig. 1,) takes the slat, resting on the bed m, m, Figs. 1A, and 2, and shoves it along on the bed m, m, under the two springs W, W, Figs. 1 and 2, passing it between the two revolving planes-one of which marked U, is seen in Figs. 1 and 2, (the other being below, and not shown in the drawings) when it is dressed on both sides.

The planes are made in the usual manner and may be made to dress the sides of the slats, in such form as may be desired. The planes are bot-h operated by one belt, f, Fig. 1, passing between the twopulleys T, T, Fig. 2 and over one of them, so as to drive the planes in opposite directions. The belt is driven by the band wheel CZ Fig. 1.

The slide V, is constructed and operated as shown by Figs; 2 and 3, the corresponding letters in each figure denoting the same parts, and the same letters, so far as seen in Fig. 1, denoting also the same parts. The spur-wheel Y, being driven by the pinion 7c, Fig. 1, and the arm, or pitman X, Figs. 1, 2 and 3, fastened to the slides V and 3 as shown in Fig. 3, gives the motion to slide V already described and also to slide 3, hereinafter described.

3. The wiring para-This part does all the wiringboth of the slats and of the rods, and consists of two stickers, a slide, and an endless chain, and the gearing by which these are all operated. The two stickers are marked 2, 2, Figs. 1 and 2. The slide is marked 3, Figs. 1 and 2 and 3. The endless chain is marked 4 Figs. 1 and 2.

Fig. 5, is a perspective view of a sticker. The sticker which wires the slats, is placed horizontally on the machine and operated the slat and thus finishes the wiring.

by the wheel 12 see Figs. 1 and 2 upon the horns 7. Fig. 1, a number of staples are placed in order, in a pile, the base of the pile resting on the driver 6, in the orifice 8 Fig. 5. As the driver is drawn out, by the revolutie-n of wheel 12, Figs. 1 and 2, 'the lower staple in the pile drops to the bottom of the orifice 9, Fig. 5, which orifice is just as wide up and down, as the staple is thick, as it lies flat on the bottom of the orifice. The slat having passed through the planes, as described above in the dressing part of this specification, is left, by the slide V,

.also above described, precisely at such a point, as that the center of one edge of the slat is at the center of the orifice 9 Fig. 5, of the sticker. The driver 6 is moved by the wheel 12 Figs. 1 and 2, and thrusts the staple, lying in said orifice 9 into the edge of the said slat. The slat is held in its place, during the operation by the spring "W, Figs. 1 and 2. As soon as the staple is stuck in the slat as just described, the slide 3, Figs. 1, 2, and 3, having passed to the left, under the slat, now takes it in the notch 3, Fig. 3, and shoves it along on the bed m, m, Figs. 1 and 2, to such a point as that the staple ust stuck rests on the rod, at the place where it is sought to wire it to the rod.

The other sticker, at this instant drives a staple, into the rod, astride the staple in rod during this process is lying in a groove n, n, Figs. 1 and 2, upon the endless chain 4 and the instant one slat is wired to the rod as just described, the endless chain 4, is moved along just the distance the staples in the rod are to be placed apart, moving the rod in the groove, when another slat is wired to the rod, as above described, andV so on, until the requisite number has been wired to the rod. This endless chain, 0f ordinary construction is moved by a pulley on the shaft 13, Fig. 2, resting in a step at 14, on which is a ratchet, or ratchet which is moved by an arm or claw which is shoved out and drawn in at regular intervals by means of an eccentric groove on the under side of the wheel 12 Figs. 1 and 2, similar to the groove on the upper surface of the wheel, O, Figs. 2 and 3, as herein above in the milling part, described. The other end of the chain passes o-ver a pulley the shaft of which is seen at 15, 15, Fig. 2.

The sticker herein above first described* of Wiring the slats, is driven by an eccentric, on the wheel 12, Figs. 1 and 2, in the usual way, and the other sticker is driven by the eccentric 16 on shaft 17 Fig. 1. The rod 6 is the driver, to this sticker. The

The

staples to this sticker are held on the lower y or to the outer staple, so as to keep the staples pressed into the orifice. The rest of the operation is as described in the other sticker'. This sticker is placed in a perpendicular position.

The slide 3, Figs. l, 2, and 3, is operated similar to the slide V above described in the dressing part, and its construction will be seen from that description and from the drawings.

A view of the gearings as represented in Figs. l, 2 and 3, will be sufiicient to understand the manner in which this part of the machine is moved. The rod is laid into the groove n, n, by the hand of the tender. So also are the staples placed upon the stickers.

General matters-The threerband wheels, Fig. 1, may be of the same diameter. All the miter wheels may be of one diameter. 'Ihe rest of the gearing will be varied to suit the thickness, length, and width of the slats, and may be readily arranged to any particular motive desired, in the three parts of the machine, so as to produce just the movement necessary, and at the proper time. The frame may be of metal, or wood, and the different part-s may be of such materials as are most convenient or suitable.

In this machine all the parts are combined, and contained in one frame. The power may be applied to the machine by a belt over a pulley placed anywhere on the shaft e, or on the shaft C, Fig. l, as shall be found most convenient. The bevel wheel B, Fig. l, is turned by a small bevel pinion on the shaft C.

The staples are supplied to the rod sticker by means of the slide placed over the hook on which the staples are astride; which slide is att-ached to the cord y having suspended atI its extremity the weight e.

What I claim as my invention and desire to secure by Letters Patent isl. The arrangement for moving the hollow angers I back and forth in performing the milling of both ends of the slats at once, combined with the slide G operated substantially in the manner and for the purposes herein specified.

2. The manner of feeding the dressing and sticking portions of the machine by means of the slide Z operated substantially as specified.

3. The method herein described of sticking the wires by means of hooks and drivers operated substantially as herein specified.

In testimony whereof, I have hereunto signed my name before two subscribing witnesses.

ELIHU R. BENSON.
